To all whom it may concern:

Be it kno .m that I, Jossrfl E. Lummma, a citizen of the United States, and a. resident of Boston, in the county of 8116011: and State of Massachusetts, have inventecl an Improvement in Metal-Casting Machines of which the following description, in connection with the accompanying drawings, is a specification, like characters on th 13 drawings representing like This invention relates particularly to.

metal casting machines adapted-for use in many different relations. While not limit ing myseli tosuch use, I have herein repre l5 seated my invention as adapted to the mam faeture of type and type-bars torwhich 1tJs peculiarly adapted.

In order that the prinelple oi my im'em tion may undexstoogl 2o close'a otthmofandillusr trate only that 1s adapts} to the casting ofi my- V mount gol gfof 1 for example, as plates, ornamental articles and'the like I will in the ensuing description set forth onl that form of my invention peculiarly a pted for the casting of type-bags, and shall limit my description thereto without in any wise so the invention.

The opening or openings 10 are in communication with the surrounding portion of the meltmg' pot, and'throngh them the molten metal enters beneath the'piston when the latter is in itselevated position'and the said s are exposed. The cylinder-like portion 9 has laterally and preferably somewhat upwardly extending from its lower end an extension 12 leading'to and through the side wall-of-ihe melting pot and there commnnicatin with a prolongation 13 l of considerable width and is herein 'sho rnas gradually increasing in Width tothe length of the longest line or bar to by the machine. 'l'he'extension 13 in an upwardly inclined direetion the opening 5 of thehibl'e.

The piston 11 may in-f any suitable I haveherein represented it at H-alhxk'lz; to which is pivotedat 16' operating lever SSg-IIT; mountedv at lfi upon a V hrsceegsem eigthwp rrm of the shj? meansof sorews or I have the Pe s m 0f ii w re ifi m igsthe forward of bonreniently gasped Q'Ythe hand "oi thelonged; new '9 stitntes i Surfaee for the movable mold member 31 Inthe disclosed em -mentg the said lower mold I a suitable number 9f 211366;?39 made'in two-super- 13 of the melting pot being of suilicient length to conduct the molten metal to said molding members.

In order to secure the forward end of the melting pot extension 13 to the table, I preferably provide said extension at opposite sides thereof with ears 24 through which pass bolts 2%" extending through the table and firmly securing the melting pot extension in place. In order to retain the metal in a molten condition in said extension 13,

I may provideany suitable means, but prefembly I provide :tgas pipe extension controlled by valve 26 and extending in aninelined direction as indicated at 27 beneath 30 and in snflicient proximity to the said extension 13 where it is provided with a suitable number of burner openings 28. Viewing Fig.

2, it will be observed that the said burner pipe extension 27 is centrally located beheath the melting pot extension 13 and that ,at its extreme forward end it is provided with a transverse member 29 having burner openings 30 therein'in suincient proximity to the extreme forward portion of said melt- 9o ing pot extension 13.

In the embodiment of my invention as hereinbefore stated, I provide two reliltivelyjmoreble mold members. Prefer ably endeis'herein shown I rigidly attach '31 to a transverse Iipor' 'flengenpon theextreme forward end of the meltingpot extension l3. This I prefembly" do a; soitable number of 'I heve xhereinrepresaited the said" mold; substantially L-shaped in cross section, the depending portion there- 7 provided; with a multiplieity of more or Iess pf which lten fdepenld hpo th of as lower moldme-m- Ifhirve herein. represented the said melthig'petextension 13 as he apro a ding 35, the

ofwhich'is cutaway as indicated zit3ti'to a angle shoulder receivingthe lower P0113101! of the upper mold member .31;

" The connecting 43 may be formed of metal intuhular form and at its lower end A is-Vshown "as having thereon a head 13o 44 pivotally connected at 45 to a trcadle 46, itself pivot-ally connected at 47 to a bracket 48 secured to and depending from one of the cross members 2 of the frame. When the operators foot is removed from the treadle 46, the weight of the mold member the connecting rod 43, etc. causes the said mold member to move into position, as shown in Fig 4, out of molding relation to the upper mold member 31. Preferably I provide the block 39 with a suitable number of dowel pins 49 represented in dotted lines in Fig. and adapted to enter corresponding sockets in the lower mold member 34, thereby insuring the exact positioning of the latter.

I provide a matrix carrier or support which preferably and in this embodiment of my invention is adapted to be manually moved along the table to and from the casting position- For that purpose. I have herein represented the table 3 as having a forward extension 50 provided with a pair of V-shaped grooves 51, 51, wherein rest correspondingly shaped projections upon the under side of the matrix carrier the weight of the carrier being suflicient to retain it in position and permitting it to be readily moved to and fro, and if desired lifted from place. Within the scope of my invention, however. the said matrix carrier may be otherwise guided.

The matrix carrier is provided with an operating handle 53 positioned between outwardly extending ears 54. to which it may be secured by bolts 55 if desired. Upon its front face, the matrix carrier is provided with two wedge shaped ribs 56 with which cooperate suitable means to hold the matrix carrier firmly in position in casting relation to the mold members While for this purpose I may emplov any suitable means, I have herein repremnted a yoke like frame 57 pivoted at 58 at the opposite sides of the melting pot extension 13. This yoke like frame is preferably provided at its 0pp0 site ends with weights 59, 59 to hold it in its inactive position as represented in full lines in Fig. 4 and in dotted lines in Fig. 1. The forward or cross portion 60 of the yoke like frame is herein shown as provided with ribs 61 adapted slidingly to g g the wedge like ribs 56 upon the matrix carrier when the latter is in molding position, and thereby securely to hold the several parts in molding relation, as shown most clearly in fill lines in Fig 1 and 3. I have herein represented the said yoke like frame 57 as haw-mg a handle 62 extending forwardly from the central portion of the cross portion 60/ While the said yoke like frame 57 may consist of a single integral piece. I have herein represented it as having two side members each composed of two parts connected together by screws 62', on one of said members entering elongated slots 62" in the other member, whereby a suitable adjustment in the dimensions of the frame may be secured. The matrix carrier in this form of my invention is represented as consisting of an upright portion 63 and the base portion 64 herein shown as integral with each other. Upon said carrier I position the matrix support proper or stick 65, and I have represented a shim 66 as interposed between the basal portion 67 of the matrix support and the basal portion of the matrix carrier. The matrix support proper is of general L shape in cross section, and I have herein shown dowel pins 68 extending through the parts 6%, 66, 67, thereby suitably to position them. As indicated most clearly in Fig. 1, the opposite ends of the matrix support proper 65 has detachably secured thereto by screws 69 end pieces 70, between which the matrices T1 are positioned in asembled relation. The said matrices are securely held in assembled position in any suitable manner, as by means of an adjusting or set screw 72 tapped into an opening in one of the detachable plates 70, as most clearly indicated in Fig. 2.

lVhile in order to define the casting relation of the mold members. I may provide any suitable means, preferably I provide the lower mold member 3; with a detachable block extending above the upper face of the mold member proper to an extent that defines the vertical thickness of the type-bar 73 when the same is in the osition shown in Fig. 4. For that purpose, I have, as most clearly shown in Figs. 5 and 9, provided a. block 75 detachably secured by screws 76 to the mold member 34. Upon the upper face 77 of said block 75. I preferably provide a. dowel pin 78 adapted to enter an opening 79 in the upper mold member and thereby to insure correct alinement of the parts. The block 75 is readily detachable, and may be replaced by other blocks of other heights, if it be desired to can a type-bar of greater (i lem thickness than that indicated in By means of the parts thus far described, a type-bar is cast that is of substantiallythe entire length of the mold members. I provide means whereby the length of the cast type bar may be varied. While for this purpose I may provide any suitable means. I have in Fig. 5 represented the upper mold member 31 as having a lateral extension 80 positioned beneath which is a block 81 having a basal flange 82 through which pass set screws 83 tapped into threaded openings Si in the extension 80 of the upper mold member 31. Between the block 81 and the said extension 80, I position a type-bar lengthmembers, and is then securely held in adjusted position by means of the set screws 83 which clamp the same between said extension 80 and block 81. The inserted end of the type-bar length-defining member covers more or less of the openings 33 in the upper mold member. and hence limits the amount of molten material that is permitted to enter between the mold members.

In that form of my invention shown in Fig. 5, the lower mold member 3-} is of a single piece extending the entire length of the longest typebar that may be cast by the machine. If desired, I may form the said member in sections, and in Fig. 6, I have represented another form of my invention wherein I have substituted for said lower mold member 3- a series of blocks 86 each secured to the underlying block 39 by means of screws 87. Preferably also I provide a dowel pin 88 for each block, thus avoiding all posibility of rotative displacement of the block about its screw Viewing Fig. 6, it will be observed that spaces are provided between adjacent blocks 86, thus exposing certain additional molten metal entrance openings 33. The efiect of such construction is to form a. series of ribs at the rear wall or face of the type-bar. Such ribs are particularly serviceable upon the typebars having relatively large characters, although they may be used with other forms of type-bars.

In that form of my invention shown in Figs. 6, F and 8, I have represented a typebar length-defining member 89 that is L shaped in eros section, as most clearly shown in Fig. 8. The inner end of said member 89 enters between the upper inl mold member 3, and the series of blocks 86 the lower mold memher. The said I -de member 89 is held in adj position 3; means of adjusting screws 90 passing through a block 91 and tapped into the threaded openings 92 in the upper mold member 31. F W'ith that fang: if my invgtionashogkn in 6, 7 an casta r t t is l si aped in cross section as indicated at 93 in Fi 11, the type characters 94 being upon the downwardly extending face 95 thereof. The said type-bar is provided with a series of ribs 96 formed between the blocks 86. Except in the respects described, the mold members and related parts shown in Figs. 6,"? and 8 are substantially the same as those shown in Figs. 3, 4 and 5.

In Fig. 10, I have shown a slightly different form of my invention in that the block 39' of the lower mold member has integral with its upper face a series of projections 93 co n in function to the blocks 86. At one on the said block 39 is provided with an upward extension 9-1 corresponding in function to the removable block in Fig. 9, and the vertical extent of which determines the thickness of the type-bar. The said vertical extension 94 is provided with a dowel pin 95 entering a hole or socket in the upper mold member 31. The type-bar castby the use of that form of my invention shown in Fig. 10 is the same as that formed by the construction shown in Figs. 6, 7 and 8.

Viewing Figs. 3 and 4, it will be observed that the molten metal is normally maintained at a level just below the lowermost holes 33 in the upper mold member 31, so that a slight elevation of the level 17, as indicated by dotted lines in Fig. 1, will force a suflicient quantity of the molten metal throu h the exposed openings 33.

I have mien-ed to the lower or movable mold member 34 as guided along the face 37 of the lower flan e or extension 34 of the melting pot extension 13. Viewing Figs. 5 and 6, it will be observed that the said surface 37 is provided with a series of vertical grooves 96. These grooves, which may be of any suitable form and number, extend upwardly between the openings 33 in the upper mold member, and their purpose is to permit the escape of air which otherwise might be trapped between the mold members and the matrices in the casting operation. While I may provide other means for the escape of air, I preferably eflect it in the manner herein described.

It will be evident from the foregoing description that the machine is of comparatively simple construction and few parts, but that the type-bars may be readily cast with exact predetermined and variable length. Moreover, not only the length but the thickness of the type-bars may be readily varied and diflerent forms of type-bars may be cast by using either that form of my invention shown in Figs. 3, 4 and 5, or that form shown in Figs. 6, 7 and 8. By reason of the fact that the parts are entirely manually controlled and operated, it is evident that the machine may be used by 3:21.11 jobbers expeditiously and economi- I may employ my invention for work to which the automatically operating machines now on the market are not. adapted, as, for instance, in the casting of very large type-bars.

In the foregoing specification, I have set forth in detail various advantages flowing from the use of my invention as a machine for casting type and type-bars. It. is, however, clearly to be understood that my invention is not limited to such use, as by suitable variation in the shape of the mold members, I may cast other articles, such, for example, as plates and ornamental objects of various descriptions Having thus described one illustrative embodiment of my invention, I desire it to be understood that although specific terms are employed, they are used in a generic and descriptive sense and not for purposes of limitation, the scope of the invention being set forth in the following claims.
